A children’s instructional book on how to use readily available materials to turn the house into a science lab
Physics teacher Bobby Mercer provides readers with more than 50 great hands-on experiments that can be performed for just pennies, or less. Turn a plastic cup into a pinhole camera using waxed paper, a rubber band, and a thumbtack. Build a swinging wave machine using a series of washers suspended on strings from a yardstick. Or construct your own planetarium from an empty potato chip canister, construction paper, scissors, and a pin. Each project has a materials list, detailed step-by-step instructions with illustrations, and a brief explanation of the scientific principle being demonstrated. Junk Drawer Physics also includes sidebars of fascinating physics facts, such as did you know the Eiffel Tower is six inches taller in summer than in winter because its steel structure expands in the heat? Educators and parents will find this title a handy resource to teach children about physics topics that include magnetism, electricity, force, motion, light, energy, sound, and more, and have fun at the same time.
PUBLISHERS WEEKLY
Mercer, a high school physics teacher, offers a wealth of ideas for how readers can household odds and ends like old CDs, empty toilet paper rolls, and plastic spoons to explore concepts in physics. The book's six chapters are devoted to forces and motion, energy, sound and waves, light and magnetism, and fluids and pressure; each experiment unfolds through straightforward numbered instructions and accompanying photos, followed by a brief explanation of the underlying science (for a "trombone" made from drinking straws, Mercer explains, "the vibrating reed causes the air inside the straw to vibrate"). More than enough to keep scientifically curious kids busy on rainy days. Ages 9 up.
